Weld
Full fake REST API generator.
This project is heavily inspired by json-server, written with rust.
Synopsis
Our first aim is to generate a fake api from the given data source (JSON). It may have bugs, missing features but if you contribute they all will be fixed.

Installation
git clone https://github.com/serayuzgur/weld.git
cd weld
cargo run
Usage
Running
Executable can take configuration path otherwise it will use default ./weld.json. If we take project folder as root, commands should look like one of these. If you you use cargo build --release version change debug with release.
./target/debug/weld
./target/debug/weld weld.json
./target/debug/weld <path_to_config>.json
./target/release/weld
./target/release/weld weld.json
./target/release/weld <path_to_config>.json
Configuration
Configuration file is a very simple json file which is responsible to hold server and database properties.
{
"server": {
"host": "127.0.0.1",
"port": 8080
},
"database": {
"path": "db.json"
}
}
Database
Database is a simple json file.

Here the owner and posts are tables. They can be empty arrays/objects but they must exist as is.
NOTE : id: Column is a must, all parsing uses it.

- Insert Record <host>:<port>/<table> POST
- Update Record <host>:<port>/<table>/<id> PUT
- Delete Record <host>:<port>/<table>/<id> DELETE
- Get Nested <host>:<port>/<table>/<id><field>/<id>... GET

Query API
Field selection
Give the API consumer the ability to choose returned fields. This will also reduce the network traffic and speed up the usage of the API.

-
max : Maximum number of elements that can be returned in a single request.

- Use sort with underscore as
_sort. - In code, descending describe as
-, ascending describe as+.
